Hi,

Just use your form keydown event.

private void form_KeyDown(object sender, KeyEventArgs e)
{
 if(e.KeyCode == Keys.Escape)
 {
  // use message box if you need.
  this.close();
 } 
}

Cheers :)

You just need to subscribe the KeyDown event handler and then you will get an event when a key is pressed. In this event you can check which key was pressed. If for example you want to close your form when "Return" is pressed, then you might use:

C#

private void KeyDown(object sender, KeyEventArgs e)
{
  if (e.KeyCode == Keys.Return)
    this.Close();
}

In Page Keydown or keyup event write code like this,
For VB,

If e.KeyCode = Keys.Esc Then
Me.close()
End If

For C#,

this.Close();
